So, checked scuttle drain and it seems fine. Noticed a wee bit split on bulkhead panel where i'd dug dry sealant out causd i'd spotted a wee touch of rust.Thinkin might be something to do with it so greased over it as temp fix.

Passenger front swimming again, cant be scuttle drain as not blocked. Any further ideas what it could be? Not the time of year i want to start stripping out carpet and hosing down so will need to soak it up till i get round to having a proper look.

its usually the scuttle area but anyway heres a daft idea. soak up as much as you can with towels sponges wet vac etc until you can dry it out properly ,carpet up job etc. however you choose.soak up some with white kitchen towels to make sure you are looking at clear rainwater rather than antifreeze although you would know if it was that anyway.now heres the detective bit.mix up a bucket of coloured water.use whatever you wish to make this.a small amount of coloured emulsion paint,food dye of even beetroot juice whatever .gently pour this over the passenger side of the scuttle area/windscreen corner so it flows down and drains out of the. bottom.hopefully!. then check inside again to see if any fresh but now coloured water has appeared. again white kitchen towels are best for this.if so then you now know that its definately somewhere in that area.check usual drain bung,seams,etc. .

be the pollen filter housing filling up.. remove pollen filter check for water and clear drains holes at bottom.. i removed grommet on inner wing to botton of pollen filter and mine never filled up again

Get a torch & a long stick and give the bottom of the pollen filter housing a good poke ..... other than a rusted out hole, it does seem as though the grommet at the bottom is blocked.

Just noticed it's wet in the back passenger side now Car sitting on slight slope downfacing so maybe leaking from back somewhere? Did have it out a run Sunday to get the cobwebs off, however front was more or less dry as I had soaked it all up and put paper on it so couldn't have run in from the front to the back.
